## Description

Package updates are available for Amazon Linux 2023 that fix the following vulnerabilities: CVE-2024-31745: 	Libdwarf v0.9.1 was discovered to contain a heap use-after-free via the dw_empty_errlist_item function at /libdwarf/dwarf_alloc.c.  CVE-2024-2002: 	In a multiply-corrupted DWARF object libdwarf may try to dealloc(free) an allocation twice. Results are unpredictable and various. This has been a possibility since we added code to prevent leaks when generating 'unattached' Dwarf_Error records (where there is no Dwarf_Debug available at the point of error). The problem was introduced in libdwarf-0.1.0 in 2021.
